So, here are my simple tips to get started:
1. Start with your cash balances... the more you can pull in the better
2. Review what customer invoices are due and particularly focus on those which are virtually certain to be paid on a certain date
3. Look at Accounts payable and other expenditure
4. Include any one-off items - check with key contacts (and especially the CFO!) for anything unusual and material
5. Adjust for any seasonality (e.g. holidays may delay payments)
6. Tag any treasury transactions and intercompany so you can get a view with and without these
7. Review and then compare actual vs forecast
